Fig. 7From: Design of a novel stimulation system with time-varying paradigms for investigating new modes of high frequency stimulation in brainNeuronal responses to another time-varying stimulation paradigm. a Similar to the paradigm in Fig. 6 but decreasing the frequency smoothly and gradually to 100 Hz after the initial 10 s stimulation, no large APS appeared. b Scatter diagrams of the normalized amplitudes of APS evoked by each pulse during the 100-s stimulationBack to article page
